-FaultDomainAwareness
Specifies at what level you want the virtual disk to be fault tolerant.
The acceptable values for this parameter are:
PhysicalDisk
StorageScaleUnit
StorageChassis
StorageEnclosure
StorageRack
For example, specify StorageScaleUnit to store data copies on separate nodes of a Storage Spaces Direct cluster.
This cmdlet refers to nodes of a Storage Spaces Direct cluster as storage scale units because you can expand the scale of the cluster by adding more nodes.
Specifies the input object that is used in a pipeline command.

-Interleave
Specifies the interleave value to use during the creation of a storage tier.
The interleave value represents the number of bytes that is written to a single physical disk.
Thus Interleave * NumberOfColumns yields the size of one stripe of user data.

The cmdlet creates the storage tier for the media type that you specify.
The acceptable values for this parameter are:
SSD
SCM
HDD
Use SCM for storage-class memory such as NVDIMMs.

-NumberOfColumns
Specifies the number of columns to use for the storage tier.
Columns represent the number of underlying physical disks in a tier across which one stripe of data for a virtual disk is written.

-NumberOfDataCopies
Specifies the number of data copies to create.
Specify 2 to create a two-way mirror, or 3 to specify a three-way mirror or for dual-parity.

-PhysicalDiskRedundancy
Specifies the physical disk redundancy value to use during the creation of a virtual disk.
This value represents how many failed physical disks the virtual disk can tolerate without data loss.
The redundancy values are as follows:
For two-way mirror spaces, the virtual disk can tolerate 1 failed physical disk without data loss.
For three-way mirror spaces, the virtual disk can tolerate 2 failed physical disks without data loss.
For single-parity spaces, the virtual disk can tolerate 1 failed physical disk without data loss.
For dual-parity spaces the virtual disk can tolerate 2 failed physical disks without data loss.

-ResiliencySettingName
Specifies the resiliency setting, or storage layout, to use for the virtual disk.
The acceptable values for this parameter are: Simple, Mirror, and Parity.
By default, when you specify Mirror, Storage Spaces creates a two-way mirror.
When you specify Parity, Storage Spaces creates a single-parity space.
To create a three-way mirror space, specify 3 for the NumberofDataCopies parameter or 2 for the PhysicalDiskRedundancy parameter.
To create a dual-parity space, specify 2 for the PhysicalDiskRedundancy parameter and Fixed provisioning for the ProvisioningType parameter.

-ThrottleLimit
Specifies the maximum number of concurrent operations that can be established to run the cmdlet.
If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer.
The throttle limit applies only to the current cmdlet, not to the session or to the computer.
